What they said about HK23 💬

Hack Kosice 2023 hosted many hackers, partners and friends. Here is what some of them said about the event.

Hack Kosice made me experience first-hand the power of collaboration in a diverse, aligned team. I would have never even thought of developing a multi-purpose app in one day by myself! That kind of self-validation pushes young scientists to take the initiative and found startups.

The event was excellent and also very different, you had a really good focus on hacker experience. I was laughing when I saw the chocolate fountain, this was the first time I’ve used one at a hackathon. 🍫 Even though big events like this can sometimes scare beginner hackers, this one is definitely up there with some of the really good ones I’ve been to.

Hack Kosice 2023 was my first-ever hackathon experience, and it was amazing! In just 24 hours, I learned so much and had a lot of fun. The atmosphere at the event was fantastic, and I was delighted with the presence of traditional Slovak dishes like “pirohy” and “halušky”. I would love to come back next year and participate again. Thanks so much for organizing such a great event!
